Gwen Turner, 29, entrepreneur and part-time barista.

Likes: true-crime podcasts, cheese-based snacks (the more unnaturally orange the better) and constantly refreshing her dating apps. Dislikes: two-day hangovers, people who refer to themselves as entrepreneurs... and discovering her latest match is actually a serial killer (probably should have put that top of the list).

They say romance is dead, but if Gwen can’t catch the mystery killer who’s targeting every man she’s ever dated, it’s about to get a whole lot deadlier. A twisty, fast-paced and darkly hilarious modern murder mystery set in the terrifying and mystifying world of online dating.
